WebWhat is FIFO Page Replacement Algorithm in C? FIFO which is also called First In First Out is one of the types of Replacement Algorithms. This algorithm is used in a situation where an Operating system replaces an existing page with the help of memory by bringing a new page from the secondary memory. WebJan 21, 2024 · FIFO Page Replacement Algorithm in C++. FIFO is an acronym for the First in First out approach. The concept is based on the fact that the elements present in the stack are removed following the same order in which they were filled. Precisely, the element present at the bottom of the stack will be removed first. ray moody nearly famousWebDec 20, 2024 · When a page needs to be replaced, the operating system chooses the page which is least frequently used for the replacement with the incoming page.
